Thanks Matthew ! for your valuable advise. To summarise, you suggested 2 things. One, I should go for test of significance between sub sample and the remaining sample instead of full sample and two, I should go for wilcoxon test.
I would like to know how to go about it in SPSS. As in most of the cases, the subsamples within full sample are more than two. If I go for analyze-->-non-parametric--> 2 independent samples, I may not get the remaining sample (that comprise of > 2 subgroups) and if I go for analyze--> non-parametric--> K independent sample, the options of the test are Kruskal wallis and median. That will again test the significance among the sub-groups and not between sub group 1 with combined sub groups 2 & 3.

Kindly suggest how to go about it ?
